Abstract

An (e.g., primary rate interface) offload device used relieve switches designed and engineered to carry short duration voice telephone calls, from servicing other types of calls (such as modem-based Internet calls), such as calls to a remote access server. Security is enhanced by isolating signaling and data communications. Such isolation may be provided by the use of separate networks, or a network with appropriate firewalls.
